Definition
Cognitiones (Latin, plural) refers to ensigns and arms, or a military coat painted with heraldic arms. The term appears in medieval English legal and chronicle sources as a descriptor for the heraldic insignia worn or displayed by armed men, identifying them by their coat of arms.
The term is closely associated with the related Latin phrase COGNITIONIBUS MITTENDIS, which denotes a distinct procedural writ in English law. That writ ran to a justice of the Common Pleas, or another officer empowered to receive a fine, commanding him to certify a fine already taken but not yet returned to the court. The writ was abolished along with the fine and recovery system in the nineteenth century.

Common Confusion
Cognitiones should not be confused with cognitio, which in Roman and civil law procedure describes the inquisitorial process by which a magistrate or judge investigated and decided a matter — a meaning entirely unrelated to heraldic insignia. Researchers encountering cognitio in civil law texts or canon law sources are in different conceptual territory. The plural cognitiones can appear in either context, so the surrounding subject matter must determine which sense is intended.

Why It Matters in Research
This term presents two distinct research traps. First, the heraldic sense of cognitiones is historically narrow: it is essentially a term of chronicle Latin, appearing in medieval sources such as Matthew Paris's thirteenth-century writings. Researchers working in English legal history before the Tudor period may encounter it in descriptions of military retinues, heraldic disputes, or narratives of armed assemblies, but it carries no technical legal weight in the common law tradition comparable to terms of pleading or conveyancing.
Second, the associated writ cognitionibus mittendis is the more consequential legal instrument for common law researchers. It belonged to the machinery of fines and recoveries — the conveyancing devices used to bar entails and settle real property — and was processed through the Common Pleas. Because fines and recoveries were abolished in England by the Fines and Recoveries Act 1833, any corpus materials touching this writ will be pre-Victorian or transitional. A researcher finding references to cognitionibus mittendis in Registers of Writs or older practice manuals should understand they are reading procedure that was already archaic or newly abolished by the mid-nineteenth century.
The sources available in the Law Mind corpus treat these terms briefly and without deep elaboration. Black's (2nd ed.) is the most informative of the three, folding the writ definition into the same entry. Neither Black's edition nor Rapalje & Lawrence situates the heraldic term in its full chronicle context or distinguishes it from the civil law sense of cognitio.

Historical Dictionary Support
All three source dictionaries — Black's (1st ed.), Black's (2nd ed.), and Rapalje & Lawrence — define cognitiones identically as "ensigns and arms, or a military coat painted with arms," each attributing the term to Matthew Paris (Mat. Par. 1250). The uniformity suggests that all three drew from a common ancestor source rather than independent investigation; none provides additional context or cross-reference to heraldic law.
Black's (2nd ed.) alone adds the entry for cognitionibus mittendis and cites Reg. Orig. 68 — the Registrum Omnium Brevium, the standard English register of original writs — as authority for the writ's existence and abolition. This is the more practically useful material for common law researchers, and its absence from the 1st edition and from Rapalje & Lawrence represents a meaningful gap in those sources. Researchers relying solely on the shorter dictionaries will miss the writ entirely.

Jurisdictional Note
The heraldic sense of cognitiones is specific to medieval English chronicle and legal sources. The writ cognitionibus mittendis was a creature of English common law with no direct American counterpart; colonial American practice did not transplant the fine and recovery system in its full technical form, and the writ is absent from American legal literature.
